12 Claims I This invention relates tomachines for knitting hosiery having reinforced portions, as a tapered high splice and sole, and more particularly to cutting and clamping means for the reinforcing yarn and it is an object of this invention to provide a cutting and clamping means, andoperating means therefor, to out and clamp the re inforcing yarn as iti's withdrawn from the needles during the knitting of one course and to release it as the yarn is presented to the needles during the knitting of the succeeding course,-the operation of the cutting and clamping means being so timed with. respecttothe withdrawal of the reinforcing yarn from the needles that the waste yarn is the same amount in each course irrespective of the number of needles taking the reinforcing yarn 'in each course.

In the drawings: Fig. 1 is a partial view in elevation of 'aScott and Williams machine for knitting hosiery with a tapered high splice and a reinforced sole which is equipped with cutting and clamp means for the vention; 1 I a Fig. 2 is'a partial top plan view of the structure shown in Fig. 1;

F'ig.'3 is a portion of the view of Fig.2 drawn to a larger scale, parts being removed in order to more clearly show the relation of the cutter and reinforcing yarn'in accordangewith this inclamp means for the reinforcing yam to the finger for feeding the reinforcing yarn;

Fig. 4 is a fragmentary vertical sectional view showing the relations of the cutter and clamp means to the reinforcing yarn finger, needles, dial and other associated members;

Fig. 5 is a fragmentary view in elevation showing part of the mechanism for operating the finger for the reinforcing yarn and the cutter and clamp means during each revolution of the.

needle cylinder in the knitting of the high splice and the reinforced sole;

Fig. 6 is a fragmentary view showing in elevato show the uniform length of the waste portion of the reinforcing yarn despite variations in the numbers of the needles taking the reinforcing :yarn in the knitting of the various courses of frame A supports a needle cylinder 260 having needles N and operated by gearing: not shown, fromzthe main driveshaft- 20 which rotates synchronously with the needle'cylinder. A dial D driven in the usual manner from the main drive shaft by a suitable driving means, not shown, is I also provided. Yarn fingers F F etc, are pivotally supported on a pin 2! mounted in the standards 55!) projecting from the latch guard ring .550. Push rods 46!! operated by cams on the main pattern drum I control operations of the yarn fingers F, F to present and withdraw the yarns from the needles.

its push rod is operated by the usual cams (not show'nlon the main pattern drum I20. The yarn finger.-Fl feeds the reinforcing yarn for the high splice 'anddouble sole to the needles and as this yarnis'fed for only a portion of each revolution .--in whichi'it is introduced to the needles means are provided for operating its push rod 460 during each of a plurality of revolutions of the needle cylinder. The push rod 460' for the yarn .finger F is provided with a projecting lug, 460 adjacent its lower end and positioned to be engaged by one end of a lever 26 pivotally mounted on a bracket 21 supported from the machine frame A. The other end of the lever 26 is positioned to be engaged by an end of a lever 28 pivotally mounted on a pin 29 fixed in a movable supporting rod 30. The other end portion of the'lever 28 is recessed, as at 28, a short distanc inwardly from the end of the lever to receive a cam 32 mounted on a lever 34 and has a projecting cam engaging portion 28 positioned to be engaged by the cam 32. The lever 3! is pivotally mounted on a pin 36 mounted in the frame A and at its outer end carries a roller 34 which is held by a spring 38 in engagement with a cam 40 fixed on the main drive shaft 20. I

The rod 30 has one end pivotally connected to an end of a link or support 42 which is pivotally mounted at its other end on the pin 36. Adjacent its other end the rod 30 is slotted, as at 30,

In the arrangement shown the yarn finger F supplies the main body yarn to the needles and to receive a supporting pin 44 which is mounted in a bracket carried by the frame A and at its end the rod 38 has, adjustably mounted therein, a pin 30 which engages a cam 48. The cam 46 and a ratchet wheel 48 to which it is fixed are rotatably mounted on the pin 44 and are operated by a pawl 50 which is connected to the lever 34 to be operated thereby and is held in contact j55'iixed'onthepin44 and engagingtheratchet wheel 48, prevents reverse rotation of the ratchet spring pawl be detent 54, mounted {on ;-an arm 2 wheel 48andcam' 48. .4 .7

The knitting continues with the reinforced portion of the sole of uniform width until the course w is reached when a movement of the main pattern drum I20 causes a cam thereon (not shown) to operate the lever 66 to shift the ratchet wheel 48 by the engagement of the pawl 64 with the pin 52. The movement of the ratchet wheel 48 shifts the cam surface 58 past the pawl 50 and permits the operation of the ratchet wheel 48 and cam 46 for the gradual widening of the reinforced portion .of the sole until the course 10 is reached. When the course w has been knit a movement of the main pattern drum I20 places the cams HI and I22 beneath the thrust rods 462 and 460, respectively, the cutter and clamp means 13 being raised first to its inoperative position and its operation stopped and the yarn finger F then raised to withdraw the yarn from the needles, the reinforcing yarn being taken by the main cutter 10 and clamp H. The operation of the ratchet wheel 48 and cam 46 by the pawl 50 continues, however, during the.

knitting of the toe until the cam surface 48 is positioned so that the pawl 50 rides thereon and the ratchet wheel 48 and cam 46 stopped in correct position for the starting of the knitting of the high splice M.

While the use of a single reinforcing yarn has been shown and described it is: to be understood that different reinforcing yarns may be used in the high splice and sole, the yarns being fed from yarn fingers controlled as described and the cutter and clamp means for the reinforcing yarns being rendered operative each time either reinforcing yarn is presented to the needles.
